I had been using MineOS Crux, MineOS+, and MineOS at times before, but on reinstalling a server found the 64 bit versions buggy at best and not working at worst. Plus the install procedures were difficult.

On the VM architecture I had previously used Ubuntu based KVM, Oracle VirtualBox and VMWare Vsphere. This is my first OS install on ProxMox VM server, so thought I would take time and document both ProxMox utilization as well as my MineOS install and preferred settings.

Linux Mint 14 XFCE and Cinnamon
The following are the Steps which I took to install Oracle Java 7, which I needed for ProxMox functionality, then reverting back to openJDK so other apps I have (don't work on Oracle Java 7) still work.

This installed Java 7, but not all my java stuff works with Java 7 yet, so for now I switch back to the default Openjdk. This leaves the new functionality of java 7 needed for ProxMox intact, namely the embedded vncviewer functions. So after we are left with a mixed setup, but it works for now, and I can switch back and forth between java versions using the command given below.

switch back to the openjdk java

java -version

this verifies the oracle java 7 is installed (if not link to tutorial)

update-java-alternatives -l

this lists the installed alternatives

note the openjdk java listed

sudo update-java-alternatives -s [name of openjdk]

this switches back to primary java use of openjdk, but keeps links to Oracle Java 7 intact for functions not supported in openjdk

will show some errors because of the missing alternatives in openjdk

java -version

this should show the openjdk java

Various command options:

Check the java version installed

java -version

help on the update-java-alternatives

man update-java-alternatives

Remove the Oracle Java 7

sudo apt-get remove oracle-java7-installer

How this is setup on Linux Mint 14 XFCE and Cinnamon

update-java-alternatives: this is the program setup for

jinfo files: java info files are used to inform the update-java-alternatives program, which is the program that is used to change java alternatives
